Common questions after upgrading from Firefox 3.6

Just updated to the latest version Firefox and wondering about all the things that have changed? This article covers the most common questions people have after upgrading and has tons of links to other great articles that you might want to explore later.

Why weren't my tabs and windows restored?

If you had tabs and windows open when you closed Firefox, the new default Firefox home page will have a Restore Previous Session button on it. To get your tabs and windows back, just click it.

If you don't use the default Firefox home page, you can restore your tabs and windows from the History menu:

At the top of the Firefox window, click the Firefox button, go over to History (History menu in Windows XP) and select Restore Previous Session.On the menu bar, click the History menu and select Restore Previous Session.At the top of the Firefox window, click the History menu and select Restore Previous Session.

When you are finished making changes, click Done to close the Customize Toolbar window.

What happened to the Status Bar?

The Status Bar at the bottom of the Firefox window has changed. The new Status Bar only shows page loading activity and link previews. When neither of those are needed it simply disappears. Please see What happened to the Status Bar? for more.

Why do my fonts look blurry?

If you are using Windows Vista or Windows 7, text in Firefox may appear blurry. This is usually due to Windows ClearType not being turned on.

In Windows, click
and type cleartype in the search box.

Click Adjust ClearType text to open the ClearType control panel.

Check Turn on ClearType and then Next to fine tune your settings.

After you fine tune the ClearType settings, click Finish to accept them.

When Firefox updates, it turns off add-ons that are not compatible with the new version. In addition, add-ons that may have been automatically installed by other programs without your knowledge (third party add-ons) have been disabled. For more info about re-enabling add-ons, see Re-enable add-ons that were disabled when updating Firefox.

Why are tabs on top of the location bar now?

How do I put tabs back like they used to be?

Right-clickControl-click on an empty section of the Tab Strip and uncheck Tabs on Top in the pop-up menu.

Why does my home page say I need to update Firefox when I have the latest version?

Older versions of Firefox used www.google.com/firefox as the home page. If you are still using this page, you will see the message, "You're not on the latest version of Firefox. Upgrade today to get the best of the Web!" at the bottom of the page. You can fix this by restoring the default home page. See How to set the home page for instructions.
